I think Push API is an industry standard but there is this W3 draft https://www.w3.org/TR/push-api/

But yes, it's essentially implemented the same across iOS/Android and browsers like Chrome, FF, Edge etc. There are services such as Amazon SNS or Google Firebase that provide a single interface which can talk to all the slightly different implementations.

In a nutshell the device registers to the server and receives an identifier token. Then a server can send messages to that identifier and the message will be displayed on the screen. Some providers allow for Icon, Audio and some Actions to also be sent as part of the message payload.

Thank you! I’ve never actually implemented push notifications. Will soon so I was wondering...
